Richards had a breakout season in 2014. With a 13-4 record and 2.61 ERA, he was generating buzz as a Cy Young contender before suffering a torn patellar tendon in his left knee in a game Aug. 20. His performance came as a real surprise, given he had a mediocre 11-11 mark and 4.33 ERA the previous two seasons as a part-time starter.

According to Gonzalez, Richards’ recovery from knee surgery is progressing well. He is expected to be ready to throw off a mound in the next few days, and should be ready for Opening Day.

The Angels have been busy in recent weeks working to sign players ahead of arbitration, signing seven arbitration-eligible players. Outfielder Matt Joyce is the one player still negotiating with the team.
